Coil whine is easy to fix , regardless where it comes from.

...Clear nail polish , varnish , conformal coating , all will fix it.

A quick dab on each coil , let dry , voila !

-----

Coil whine is not 'caused' by anything except poor quality varnishing at the factory....'dirty power' etc , is irrelevant.

Yes the nail polish mod is the trick, just beware of potentially voiding your Warranty.....been lucky so far this past few years:
PC P&C 750W
Corsair HX 1kW
Corsair AX 1.2 kW

No whine at all, I have read a few folks with the initial release of the AX 1.2kW were suffering this problem and of course Corsair provided the necessary RMA ......

+1 for the line conditioner anyway. Still useful regardless of the whine cause.

I recommend a step up from line conditioner and just buy a straight up UPS.
